GBCC vs SameBoy

GBCC is a free Game Boy and Game Boy Color emulator written in C, with an emphasis on accurate emulation. It runs on Android, Linux, macOS, and Windows, with SDL and GTK graphical interfaces. Visual options include Dot-Matrix, Colour-Correct, and Subpixel shaders, DMG palettes, and frame blending; Colour-Correct and Subpixel are intended to reproduce Game Boy Color output accurately. It supports gamepads, adjustable turbo, screenshots, a VRAM tile display, cartridge saves with real-time clock data, and save states with automatic saving and resuming. Link emulation connects GBCC to another instance of itself. The Game Boy Printer sends output only to the terminal, and Game Boy Camera support is limited to Linux and Android. Game Boy Pocket and Super Game Boy are not supported. Installation options vary by platform, and the project describes development as ongoing but slow. Save states are binary dumps and may not work across different architectures or compilers.

SameBoy is a free, open-source emulator for Game Boy, Game Boy Color and Super Game Boy systems. Its supported machines include Game Boy Pocket and Light, Game Boy Advance and Game Boy Player in Color mode, and Super Game Boy 2. The project describes its design as focused on accuracy and says it passes multiple test ROM suites. It supports battery saves and save states that follow the BESS specification, as well as turbo, rewind, slow motion, cheats and rumble. Peripheral emulation includes local link cable, infrared, Game Boy Camera, Game Boy Printer and Workboy. Display options include scaling algorithms and filters, customizable controls and fullscreen mode; an integrated GBS player is also included. Developer tools include a disassembler, expression evaluator, breakpoints, watchpoints, call stack tracing, and memory and video RAM viewers. Builds are listed for macOS, Windows and iOS, and the project describes SDL support for other operating systems. Some features are exclusive to the macOS Cocoa frontend, while camera and printer emulation are available in Cocoa macOS and iOS frontends.
